Escherichia coli

Escherichia coli (E. coli) is a bacteria that is present in the human body. Can potentially be dangerous, especially if you are caught outside the colon where it normally is.

Escherichia coli (abbreviated E. coli), which was discovered by a pediatrician and bacteriologist Theodor Escherich, is one of the main species of bacteria that live in the lower digestive tract of mammals. Necessary for proper digestion of food and participate in the intestinal flora. Its presence in groundwater is usually an indicator of fecal infection. Belongs to the group of Enterobacteriaceae and is often used as a model organism for bacteria in general.
Technical coliforms are defined as aerobic and optionally anaerobic, nesporogene, gram-negative, rod shaped bacteria that ferment lactose and pushing for 48 hours at 35 ° C produce a product gas. In the body of this gas is released as flatus. E. coli cells are elongated, the length of 1-2 mm and a diameter of 0.1-0.5 μm.Zbog its omnipresent E. coli is frequently studied in microbiology, and increasingly also in molecular biology. Its structure is quite well known and as such represents an excellent starting point for students of natural znanosti.E. coli plays an important role in modern biological engineering. Researchers often use bakerije as factories to produce large amounts of DNA and / or protein. One of the first major application of recombinant DNA technology was just genetic manipulation of E. coli for the production of insulin in patients with diabetes.
